Screenshot of issue

As seen in the attached sceenshot Google Reader appears to contain the tops of random pieces of text below story headlines. The black shapes remain when the story is opened.

This started occuring within the last month of Nightly Builds. The problem didn't present itself in Safari 4 but does in Safari 5.

Thanks for reading.

It appears to be the top of the second line of the "snippet" span.
